26 Claims. 1 v

This invention pertains to improvements in machines for and methods yof applying a coating to shoe parts and is illustrated herein, in its machine aspect, as embodied in an improved counter pasting machine of the type disclosed in an application Serial No. 512,924, led December 4, 1943, in my name, and towhich reference may be had for details not more fully disclosed herein.

In the above-mentioned application there is illustrated and claimed ka machine for applying adhesive, hereinafter called paste, to a premolded counter in asemiautomatic manner, said machine being used in conjunction withheel-seat lasting` machines tovfurnish freshly coated counters at a rapid rate and is such timed relation Awith the heel-seat pulling-over and lasting operations that a freshly coated counter will in readiness for the succeeding Y aforesaid prior machine includes a pairof oppositely disposed parallel applicator brushes, furnished with paste and between which the diverging legs of the counter are moved in succession. A reciprocating crosshead is provided for moving the counter linearly with respect to the applicator brushes, open end first, to advance one leg of the counterbetween the brushes, then to rotate the, counter as the rounded end reaches the brush engaging the inner side of the counter, and thento continue the linear movement of the counter in the same direction, rounded end rst, to `draw the other leg between the brushes. of the crosshead is then reversed and hence carries the counter back to itsstarting point, the linear and rotation-al movements of the. counter Y being duplicated in opposite directionsso that two coats of paste are applied. For reasons which appear in the priory application, it is desirable to omit theapplication of paste to the yupper margins and especially to the inside and outside marginal surfaces of the legs of the counter adjacent to their ends. This was accomplished in the prior machine by arranging the supporting means so that it held the counter .with one leg at an angle to its path of movement relativeto the applicator, the angular position of the counter constantly be operation. The

i n 2 substantially tangential. Hence, the applicator, which, as illustrated, is a brush, so lightly engaged the leg of the counter adjacent to the uncoatedl area upon initial contact that the thicknessof the paste applied at this point was very thin.

An object of the invention is to provide animproved coating machine for progressively applying a coating toa piece of work, by relative movement between an applicator and a work holder, Y,

which will insure an adequate coatingV at one point in the progressive operation by increasing the pressure between the Work and the applicator. By such an arrangement, it is possible to obtain a heavy coating of paste at, for example, the line of initial engagement between the applicator and a piece of work, such as a shoe counter. f l n In order toenable the progressive application a band ofcoating material of uniform thickness which may be spaced from the edges of the wor thereby leaving a bare margin, the machine is arranged, in accordance invention,v for relative movement between a work holder and an applicator movement between the work holderv and the ap- I plicator in a direction different ,from the direc- The movement i being such that the marginal portion of the l counter leg adjacent to its advancing end lay outside the sphere of action of the applicator and hence thisportion remained uncoated. `In some instances, because of the an-gle at which the leg of the counter approached the applicator, there was some fuzziness between the coated area of the counter leg and the uncoated marginal portion thereof, due to the fact that the initial cntact between the applicator and the counter wasl tion of progressive coating movement to bring the Work and the applicator firmly together at one point, 'such as at the timeof initial engagement between the two. As herein illustrated, the applicator is in the form of a driven rotary brush and the work carrier, movable in a predetermined path to present the leg of the counter substantially tangentially to that brush inside of a bare marginv on the counter, is arranged to tilt the counter rmly against the brush at the point of initial contact and again adjacent to the pointv of separation ,between the brush and the counter.

As in the prior machine, the machine of the present vinvention includes two applicators, such as driven rotatable brushes, one of which is also movable bodily. One of the brushes is supplied with paste directly, and the other receives a supply ofA paste from the first brush during those periods when no work is passing between them. The bodily movable brush receives paste directly from a paste container herein, however, and in accordance with a feature of this invention, means is provided for extruding paste Vfrom the container onto the surface` of the brush.- As illustrated, thisis accomplished automatically by an extrusion member associated with the container. andY operated by the movement of the counter holding and clamping means to force the with a feature of thef and for additional.`

` furnish additional paste to which consists in bringing. together member and an applicator member by relative contactibetween'thev i Work; and the Y applicator andA in thenV imparting paste through a plurality of openings in the bottom of the container onto the surface of the applicator brush and in such timed relation with the `movement of the counter holder that the paste is l applied to the brush when the counter holder and clamping Vmeans is at its loading position and hence out of contact withthe brushes.

Adjacent to the perforations 50, on the inside of the receptacle (Fig. 6) is a shoulder 52 which extends vertically from the bottom of the receptacle for the full width of the perforations, the shoulder having a horizontal surface 54 adjoining its vertical surface. Through the opposite end of the receptacle there is formed an opening 56 in Whichthere is slidably mounted a flat valve plate 58 adapted to slide on the bottom of the receptacle to and from the aforesaid shoulder. At the inner end of the slide there is an enlargement 60 having a recess on its under side bounded by parallel side walls 62 (Fig. 2,), a rear wall 64, andy a top wall 66 which form with the bottom of the receptacle an open-ended rectangular chamber 68. The heightof the chamber 68 is such that, as the valve plate is' moved toward the front of the machine, i. e.v the left in Fig. 4, the top and side walls will telescopically slide over the shoulder 52 adjacent to the perforations in the bottom of the receptacle. With the aforesaid construction, when the valve plate 58 is withdrawn to the right to the position shown in Fig. 6, the paste in the receptacle will gravitate to the bottom and ll the open-ended chamber at the end of the valve plate. Upon movement of the valve plate 58 to the left, the open end of the chamber 68 will be closed by the shoulder 52 and, as the movement to the left is continued, the volume of the chamber will decrease and the paste therein will be extruded through the perforations 50 directly upon the applicator brush I8. A rectangular, sleeve-like partition 10, having top and side Walls adapted to surround the slide valve adjacent to the opening through which it slides in the end of the receptacle, prevents escape of the paste through the end of the receptacle. The aforesaid slide valve 58 is operated automatically to extrude paste at the proper time for application to the applicator brush I8 when the latter is not vengaging a counter, or alternatively manually. The specic construction of the means for operating the valve will be described hereinafter.

While the slide valve 58 for extruding the paste from the receptacle is ordinarily automatically operated,v as will appear further on, it may be desirable to load the applicator `brush I8 with paste prior to setting the machine in motion, or at other times during the operation of the machine, independently of the automatic means. Such independent application of paste' to the brush is provided for by manually operable means. This means includes a pair of rods v'I2 (Fig. 2) at opposite sides of the receptacle adapted to slide in bosses I4 formed at the lower corners ofl the receptacle. p their opposite ends by horizontal bars 1,6 Which may be grasped by the operator and afford means for sliding the rods longitudinally within their bosses; One of the bars -.'10, namely, that shown at the rightin Fig. 2, is fixed to the free end of the slide valve which projects from' the receptacle. By grasping one of the bars andY pushing the rods from right to left, as seen in Fig. 6, the valve may be actuated to extrude paste. Itisapparent that the positiveextrusion of a given quantity of paste from the receptacle each time, either by the automaticmeans or by the manual paste to the applicator brush regardless of the temperature or viscosity of the paste and thus insures a uniform supply to the applicators at alltirnfes.` p .Vi Y

Thecounter Cv, as shown in Fig ."7, ,isv preformed The rods are connected atv .l application of paste to means just described, permits applying a definite quantity of Viirst contacts the brush and `has diverging legs joined Iby a rounded back part, and in the illustrated machine, as in the prior machine, movable supporting means I6 is provided for holding the .counter and moving it, open end rst, in a linear direction to advance one leg between the brushes I8 and 20 untilthe inner surface or" the rounded back part substantially engages the brush 20, then to krotate the counter to bring the other leg into Va corresponding position, and, finally, to'` resume' the linear movement of the counter in the same direction, rounded end rst, to draw the other leg between the brushes. As in the prior machine, the counter holding means I6 includes a` rotatable V-j shaped support (Figs.` 3 and 8) yhaving a groove 82 to receive'thebottom ange 208 (Fig. 7.) ofa counter C, and a clamping means 18 to grip the upper .margins 200, 202 thereof. This clamping means T0 is rotatable in step with the support 80 and comprises clamps 86 (Fig. l) to hold the upper margins of the legs of the counter against a V-shaped block 84. In order to prevent the the inner-margins 204 of the curved portions near the ends of the legs, the counter holding means I6 is constructed to hold the legs of the counter at an angle of about 20 to the horizontal and, as a result, these margins 204 of the counter lie outside the field of action of the brush 20 and-when theends of the'legs are moved across the brush, those portions .do not engage it. In order also to preserve theend margins 206 of the outer surfaces of the legs free from an application of paste, the brush I8, adapted to apply paste to the outer surface ofA the counter, is moved up and down in timed 'relation Witv the movements. of the counter tobring .it into contact with the legs back of the marginal end portions.v 208 thereof. f

While the angular position of the counter with respect to its direction of travel causes the end marginal portion of the advancing leg to pass above and beyond the applicator brush 20without receiving an application of paste therefrom,- the initial contact between the two is verylight,

due to the fact that the applicator brush is comflexible bristles which excenter of rotation of the posed of a plurality of tend radially from the brush. In other words, counter approaches the applicator substantially tangentially thereto, it is'found that the pressure is so light when the surface of the counter that there is substantially no application of paste. As a result, there is no clear line between the uncoated area 204 at the marginal end of the leg and the coated area at the rear of this marginal portion. This is undesirable because the adhesivebond between the .counter Iand the lining and upper material at this point would be weakened by this lack of, paste and would constitute a starting pointfory the lining material to pull away from the counter. The improved machine illustrated herein overcomes this undesirable feature by insuringl an application of paste at the point of initial contact which Will be of equal weight to that which will be applied to the remainder of the counter, and this will be accomplished, as will appear hereinafter, by imparting a secondary movement to the counter holder and clamping means, as initial engagement is established `between the counter and the applicator, to press the counter into intimate contact with the applicator. 1

The cros'shead 94 is reciproc'ated to carrythe counter direction and then in the other direction.

f The axes of rotation `of the counter clamping means 'I8 and the support-8`0 are coincident, the countersupport 8E) being .'xed to sleeve 83 supported on the upright 9| (Fig. 3) for rotation about anV axis coinciding at that time with the axis of the brush 20, and the counter clampingmeans 18 beingrxed upon a horizontal shaft `B8 which is rotatably mounted'ina split bearing `90, the latter being formed integral with the upright 92 on the crosshead 9'4. The split bearing 90 is provided with a pair of bosses 96 which are joined by a bolt 98, the bolt passing through aspring IUI] and then loosely through an adjacent boss and being threaded into the other. By rotation of the bolt, the elements of past the` applicator -r'st .in one a horizontal and 92 ofva cross 3 applicator brushes Yto advance one leg of the counter v,between the applicator brushes, then dwells While lthe counter l other leg into Vposition the bearing may be drawn together about the shaft 88 yieldably to grip the shaft, the adjust;v ment of the bolt affording means for varying the frictional resistance to rotation of the shaft. VThe' crosshead 94 which carries the counter support Brand the clamping means 18 isV mountl edfor movement ktransversely of the 'applicator brushes,y I8 and 20 upon a pair of horizontally disposed parallel rods |02 (Fig. 8) ,the rods being supported at their opposite ends -at-the 'front and rear ends of the rectangular frame I0. The .transf verse or linear sliding movement of the crosshead 94 along the rods IZ from front torear moves Y.

the counterfrom its initial or loading position at the front of the -machineatthe left inFig. l, with its openend toward the 1 right,- toward .the the upper flegdispos'ed at an angleof 'about 20 to the horizontal. vLinear movement of thev crosshead with the Ycounter in thisV position brings the aforesaid leginto contact with 'the ybrush 2i] whicha'pplies alcoatin'g to the inside of the counter at a point back of its leadV Y IC() 5, Vsince the leadingedge and the-marginal portionV ing edge, as will be seenby. reference 294 adjacent theretopass above `andbeyon'd the brush without-'making contact with @its surface as the counter is moved horizontallyxfto the .right toward the brush. lHence;this. marginal portion Y remains uncoated.

' At' the .moment vtliatcontact-is established between thecounter andthe applicator, las' shown inFig. 5, and, in'contrast tothe prior machine, a secondary movement, which vvcomprises V.a lfurther partial rotationof the counter holding means "i6 about its axis, Vtakes placeV in such-.a manner' as tov force the 'surf-ace of vthe counter int'o'intimate 'contact with the-'applicatorbrush,as`illus vthis secondary movement movementuntil the brush'fZe engages the'olo'sed,

` counter' :whiennnngs the etherrleg the counter into aposition reversely inclined to thatvof the first leg of the counter, that is, so that this latter leg makes an angle oflabout'z" to the horizontal. After this rotation is completed, the crosshead resumes its linear movement in the same direction and the second leg is drawn between the brushes and disengages thelower brush 20 at a point which precedes the trailing end of this second leg. Hencaa marginal `portion VZllllon the second leg is also left uncoated.

VDuring the coating of the inner surfaces of the legs, the 'outer surface is also coated, the upper brush I8 being moved, up and down in timed relation 'with lthe movement of the counter so that contact is madewith-the first leg at a point spaced from the advancing end and .substantially oppositeto the Contact of the brush 20 with' the inner surface of the leg, .and contact is broken, by' raisingthe brush `I8 at a corresponding point on the.v opposite leg.

Asi-in the earlier machine, the travel of the crosshead 94 land the partial rotation o the counter holding means I6 during that travel'is effected by means of a chain `drive comprising chains stretched from front to'rear of Vthe Amachine associated respectively with the counter holding 'means 89 and the counter clamping means 18. One chain.II2, which is at the left side of the machine, the top side in Fig. `8, has both its end portions partially wrapped around a pulley II and secured thereto. Y This pulley, as may be seen'from Fig. 3, is mounted 0in the hollow shaft 83 which carries the counter holder-80. The pulley II@ has two grooves `and the ends of the Vchain are fastened in these grooves. 'The chain H2 y.passes over a pulley |08 at the front end of the machine, extends.Y along (Fig. l)Y the frame to the under side of a svp-rocket |09 at Ytitle rear end and lthen 'passes around the sprocket and 'back to the pulley II. The pulley I'08 is supported on a stud IBS carried by a post I |34. 7 A reversible belt drive I I5 (Fig. 8) is connectedwith the sprocket at the rear end of the machine and is adapted to be controlled as to ydirection of rotation vby .a belt shifter I Il which may be moved `by means of a'lever II9 connected to a manually operable rod IBB (Fig. 1 'or by suitable contact between the 'crosshead Sil and pieces suchas' the lever H9 associated with that rod. Asa conse; quence, the crosshead travels fromY the position shown in Fig. 1 toa `position at the other yend of the machine and then the belt drive is reversed and the cro'sshead is returned to the startingv position. A similar chain I I3 along the 'right side of the` machine, the neariside in Fig. 1, isfassociated with a similargrooved pulley III mountedon the shaft 88 of 'the counterY clamping means i8 vand passes over'aA pulley II' on afpost'lll anda sprocket IZI at the rea'r end (Fig. '87).Y

In 'the prior "machi-n'ejthe counter holding and clamping vmeans are rotated at one point the linear movement of Y Jthe crosshead when the' rounded, `closed end of' the counter reaches'the applicator brushes. 'This is accomplishedy bya pair of levers `I20and -I22 "(Fig. 1) whiclfi are pivotally Afastened to the frame I0 at |24 and I2`6, the lower ends being urgedvt'oward each `otherlby a spring I`28 'which lisfast'ened 4b'etvfeenl'hem.V The upper ends of the levers bear onthe under? side of a horizontalbar 130 y'(Fi'gs. l and 8) which is fastened to the crosshead and moves therewith, and are adapted to engage n'otchesfl'ZA vformedin the underside of the bar. `During movement of the crosshead toward the rear of the machine,

thatfis, tothe right as seen' in Fig.Vv V1,"tlie'lei`ler |22 will engage the right-hand notch |32 and arrest the linear movement, whereupon continued 'movement of the chains I2 and 3 will start rotation of the counter holding and clamping means I8 about the axis of the sleeve 83 (Fig. 3). In a disk |31 fast on this sleeve Vis a pair of stop screws |34 and |34' (Fig. 4) threaded through radial lugs |36 formed integral with the disk. After approximately a half rotation clockwise, as seen in Fig. 4, of the counter holder, the screw |34' will strike the lever |22 and push it down out of the notch will continue its linear movement to the rear of the machine. 'Ihe movement of the counter holding and clamping means during its approach to the brushes and after it has passed beyond the applicator brushes is restricted to linear movement by the frictional resistance to rotation of said holding and clamping means alforded by the split bearing 90 drawn 4 about the shaft 88. When the lever 22 rises into the notch |32 Vand temporarily stops the linear movement of the crosshead toward the center of the machine, the frictional resistance to rotation of the shaft 88 in its bearing 90 is overcome and rotation takes place until the screw |34 moves the lever |22 out of theA notch. On the reverse movement of the crosshead from the rear tothe front of the machine, that is, from right to left as seen in Fig. l, the lever |20 performs a similar-function so that the counter is again rotated as it passes the applicator-brushes. A screw |35 on the disk |31 then ablitsthe top-of the bar |38 and determines the initial position ofthe counter holding means |6 with the top of the counter leg at an angle of 20 to thehorizontal, as before described.

In the improved `machine herein described, means is provided for imparting a partial 'rotation to the counter holding means 80 and the clamping means 18- just -before they reach the above-mentioned means |`22 for producing: the approximately half rotation ofthe counter in'order to reverse their direction of movement and cout the trailing leg. This means is similar to the aforesaid means and, as illustrated herein, comprises a pair of yieldable levers |38 (Fig. 1) pivotally mounted at |40 onthe frame of the machine in positions symmetrical tothe brush shaft 24. Each lever has acam` surface |42 which occupies a position in the path of"Vv movement of the counter holding means so thatjas a 'counter approaches the applicator brushes, the screw |34 carried by the disk |31 strikes the cam surface of one of the levers '|38 and momentarily resists the linear movement of the crosshead. A partial rotation of the counter holding and clamping means immediately takes place. Since the period of contact between the lever and the screw is very short, the rotation is slight, buty is sum.- cient to force the counter into contact with the applicator brush, that is, from 'the position-indicated in Fig. to that indicated-in Fig. 4. The crosshead then continues its linear movement toward'the applicator and whenthe lever |22 falls into the notch |32 la half rotation of the counter holding and clamping means'takes-place, as previously described. In its reversed position,

the counter holding andl clamping means con-` tinues on by or beyond the applicator brushes and the screw |34 strikes the secondv lever |38 but, since this lever is yieldable Vinthe direction of motion of the counter holding'and clamping means, the screw passes bythe' lever without producing further rotation of the counter holding and'clampingimeansf-fOngthe reverse* direction 'H5` |32, whereupon the crosshead of movement of the counter holding and clamping means, this second lever 38 will'strike the screw ,|34' and produce a partial rotation in the reverse direction of the counter holding and clamping means so that the opposite leg of the counter is also insured an adequate application of 4paste at its initial Contact with .the 'brush 20. vThe lower ends of the levers |38 are extended and joined together by apin |44 'upon which there is mounted a coil spring |46 (Fig. 4), the latter being disposed `between the levers on the pin, thereby permitting movement of the upper ends away from each other.r To prevent movement of the upper ends ofthe levers 38 toward each'other'when the screws |34, |34 'on the disk |31 strike them, as in Fig. 5, adjustable stop screws |48 are provided which are threaded through a bracket |50 fastened to the upright 30. By adjustment of these screws |48 and the screws |34, |34 in the disk 31, the amount of rotationv of the counter 'holding and clamping means may be varied. 'I'he pinY |44 is vkept in place by cross pins outside of the lever ends.

As' in the prior machine, the upper brush I8 is somounted thatV it may be moved into and out .of contact with the legs of the counter in timed relation with the movement transversely thereof. To permit such movement, as heretofore described, the upper brush I8r is mounted in the sleeve bearing 2'8 (Fig. 3)v which is tiltable to and from the lower brush 20 about a horizontal pivot 21. The movement of the brush I8 to and from the brush 20 is controlled bythe combination of the spring-pressed plunger 312 and a bar cam |52 (Fig. 1), the .bar cam being fastened to the upper ends of a pair of vertical Vposts |54 which, jin turn, are, set into recesses formed in the sides of the post92 'on the near end 'of the crosshead 94, as seen Yby reference to Fig. 1, and held there by `screws, |56 and,` a through bolt-| 58. As will be .seen by` reference to Fig. 3, the shaft 22 extends throughfrom thepback `ofthe brush I8 to'the front thereof `and has mounted thereon a ,freely rotatable sleeve, |62 which is held against the under surface of the bar cam |52 by the springpressed plunger 32 which urges the bearing sleeve 26, arid consequently the shaft 22 of the brush I8, in a counterclockwise direction about its pivot. lThe lower surface of the cam |52 isso shaped that, when the crosshead is at its initial or loading position (Figyl), that portion ofA it surface designated a holds the brush 8 in engagement with the brush 20 in opposition to the spring-pressed plunger ,'32 Vsothatthe brush 20 will receive paste from the brush I8. When' the machine' is started, the cam |52 moves to the right, vras seen in Fig. 4, and the sleeve |62 follows the upward slope of the surface marked bv so4 that, when the leading end of the counter is approximately adjacent tothe entrance side of the brushes, the upper brush 8 to the position spaced from the ybrush 20,* as shown in'Fig. 4. Hence, the brush arated from the brush 20 and it does not contact the leading end of the counter. At this position, the sleeve |62 occupies the portion c of the barl cam. 'Further movement of the crosshead forces the sleeve |62 downwardv by reason of its engagementv with the downwardly sloping surface d of the cam so that the brushl I8 isbrought` into engagement with the outer surface vof the counter after the end'margin 206 thereof has passed and, at the portion e, thev brush |8 is held in a fixed position during the rotation of of the counter `will have risen i (Fig. `l), as in the previous machine, L the crosshead .64 moves rearwardly, i right as shown in Figs.

` the counter asits closed' end is coated. As the other leg of the counter is withdrawn from between the brushes, the brush I8 is allowed, by

'the sloping surface f, to rise out of' contact with the counter, vjust as the trailing marginallportion 206 of the leg reaches the brushesg `On the return movement of the crosshead, the brush |8 is actuated in the same manner by the portions f, e and. d to again treat the outer surfaceof the counter, whileV leavingthe end ymargins bare.

Yhaving an uprightarm |66 fiXed thereto, the arm having a passage |66 therein for the reception of a `horizontal rod |10, the latter being attached to the valve slide .58'. As will be seen, the end of' the rod |10 is threaded into the horizontal bar. 16 and is locked inplace by a ynut |12. YBetween theY nut |12 and the upright arm placedfa coil spring |14. At the free end of the rod |10 there is placed another. coilspring |16 which is prevented from sliding off the end of the rod by a collar |18 fixed to the end of the rod. By the aforesaid construction, when the counter holding and clamping means is at its initial or loading position at the front of the machine, the bar cam |52 to which the aforesaid arm |66 is fastened will be at its eXtreme'left-hand position and will yieldably force the valve-plate 63, as illustrated in Fig. 4, toward the shoulder 62 thereby to extrude paste from the bottom ofthe .receptacle through the perforations 50 onto the surface ofthe upper applicator brush I6. At this partcular time,'no work is passing between the applicator brushes and, since these brushes are rotating,-

rapidly, the extruded paste will .be delivered I8 to the lower. brush 20A evenly by the top brush and, .when the counter holding and clamping means beginsrits movement `to the right with a fresh uncoatedV counter be loaded with paste for application to the surface vof the counter. As the counter holdingV and clamping means proceeds to the rear of the machine,.the bar. cam carrying the arm |66 will draw the Vrod |10 toward the right, thus pulling the valve plate 58 to the right so .that it occupies a position, as shown in Fig.. 6, in which a fresh `quantity of paste will gravitate into the chamber.- `The springs |10 Aand |16 yieldably permit full` travel of the crosshead 94 without the necessity :of exact adjustment vof the contact between the arm |66 .and the stop portions of the rod |10. Upon Areturn movement of the counter holding and clamping .means Having inserted the bottom flange of `a counter (Fig. l) ofthe clamping means 1:8, the machine .is set in operation by pulling forwardly on a rod. |80 whereupon or to vthe y l and 8. During the .initial movement of. the crosshead, the counter .holding Q andclamping means I6 occupies the 4position 'lvshown in Fig. 1,..in which the upper leg vof the counter makes an angle of substantially 20 with,

1 the horizontal. -As the crosshead advancesopen end first, the-bar cam v|52 moves forwardly and |66y there is therein, the brushes willy e to the left, that is, to .the lfront of the machine again, another quantity ofpaste willbe extruded.

Vinner surface of. the

.g is drawn between-the brush I8 is lifted by lthe outside surface of the counter so that no vcement is applied to the vversed position occupies the machine, or to the left as allows the upper applying .roll I8 to rise away from the lower roll 20 so that the end ofthe advancing legY of the counter moves between the brushes without contacting the same. As the leg con.- tinuesY its movement between the brushes, the leg beginsto contact the brush 20 back of the uncoated margin 204 thereof as shown in Fig. 5, rand at this point the counter clamping and holding means |6 is given a partialrotation byy reason of the contact. of one of the screws |34 with onel of the leversv |38 so that the counter is brought positively into contact with the brush,.as shown in Fig. 4. Simultaneously, the upper brush is brought into con- 'i tactv with the outside surface of the counter at substantially the same point thereon with relation to the end of the counter.. The longitudinal movement of the crosshead continues until the rounded inner end of the counter comes intocon'- tact with the smaller brush 20, whereupona complete reversal ofth position of the counter takes place -by engagement of the lever |22 with the rear notch |32 in the under side of the member |30. After reversal of the counter, the opposite leg brushes until, near the end 'the crosshead, the upper the spring plunger 32 from of the movement .of

outside margin 206 near the end of the leg. Since the counter-in its rethe; same angle' with .respect to the horizontal as it did in its initial lposition, the inside of thele'g ofthe counter remains.

uncoated as it leavesY the sphere of action of the brush 20. As in the previous machine, automatic means is provided for reversing the motion of the crosshead so that it travels to the front' of during this returnl movement, the counter. goes through the same partial rotations and tilting movements that itdid during the rearward move ment, thus insuring a positive application of cement on the inside :surface of the opposite leg adjacentt'o its end.

` During the travel of the crosshead from and to the front ofthe machine, the upper brush I8 is supplied with paste fromthe container .3.8 positively by means of the valve 58. lThis valve is i operated by the motion ofthe crosshead and,.

' '1 horizontal bars when the'crosshead is at the extreme left or frontv end ofA the'machine, as seenin Fig. 4, the valve is completely closed. As the crosshead moves to.-V

ward the right, the valve remains closed untily the arm |66, which is carried by the bar cam |52, comes into engagement with the .spring |16 on the vrcd'10, whereupon the valve is pulled open. to the position shown :in Fig. 6 and paste grav-v tates to the bottom of the receptacle, lling the chamber 68. Upon the reverse or return move.- ment of the crosshead to the front of the machine, the valve is closed to `extrude the paste by engagement of the arm 66 with the spring |14..
